Coastal and Floodplain Construction Inspector's Practice Exam

What is the minimum size of square piles on the side where the exposed length is equal to or less than 12 feet?

1. 6 inches

2. 8 inches

3. 10 inches

4. 12 inches

The correct answer is: 8 inches

The minimum size of square piles on the side where the exposed length is equal to or less than 12 feet is 8 inches. This specification is typically based on structural engineering principles that ensure adequate load-bearing capacity and stability for the pile in the given conditions. When dealing with exposed piles, various factors, including load, environmental conditions, and material properties, dictate the size requirements. A minimum dimension of 8 inches for square piles helps to ensure that the piles can effectively resist lateral and vertical loads while also providing sufficient durability against conditions such as erosion or impact. Choosing a size smaller than 8 inches may compromise the structural integrity of the pile, potentially leading to failure under operational conditions or extreme weather events, which are particularly relevant in coastal and floodplain regions. In this context, adherence to established minimum standards is crucial for ensuring long-lasting and reliable construction practices.
